Forerunner 305's courses feature lets you compete against previous workouts: you can compare your pace and heart rate to your past performance over the same run. You can also use Forerunner 305 to train for your next duathlon or triathlon with multi-sport workouts, a feature that lets you seamlessly transition between sports without resetting the unit, so you can use it for running, biking and more.
Train indoors and still track your distance, pace and calories burned with the optional Foot Pod accessory. This wireless sensor attaches to your running shoe and transmits distance and pace data to your Forerunner 305 so you can still use it when GPS reception is unavailable. You can customize any of Forerunner 305's three main data screens — up to twelve data fields give you instant feedback on your workout. And, as with every Forerunner, each workout is stored in memory so you can review and analyze the data and see how you've improved over time.
